Abstract (en)
[origin: EP0423811A2] In a sheet transport unit for recording systems which uses a pulse motor (8) to feed a recording sheet (2) quantitatively and intermittently, multiple different current apply intervals are specified within the stop period during intermittent sheet feed, so that a maximum amount of current will be applied to the first interval immediately after the drive stops. Thereby, the pulse motor (8) is never be damaged due to its temperature rise despite a load variation and the load variation can be absorbed enough to ensure high positioning accuracy.
